Dengue is the most prevalent viral infection transmitted by Aedes mosquitoes. More than 3.9 billion people in over 129 countries are at risk of contracting dengue, with an estimated 96 million symptomatic cases and an estimated 40,000 deaths every year.

Prevention tips Use insect repellents any time you are outdoors. Wear long-sleeved clothing. Schedule outdoor activities to avoid the hours from dusk to dawn during peak mosquito season. Repair damaged window and door screens. Remove standing water from the areas around your home.

How can these bugs—so tiny that we often miss them at first swipe—be responsible for so many infections? It turns out their vampire-like tendencies are largely to blame. “Mosquitoes literally drink blood, and by doing so ingest microbes directly and can pass them directly into the bloodstream of others,” says Dr.

Roughly 390 million people are infected each year with dengue, and hundreds of thousands more are affected by Zika, chikungunya and yellow fever. Common types of mosquito-borne diseases include malaria, dengue, West Nile virus, chikungunya, yellow fever and Zika.

The parasite infects female mosquitoes when they feed on the blood of an infected person. Once in the mosquito's midgut, the parasites multiply and migrate to the salivary glands, ready to infect a new person when the mosquito next bites. Malaria remains one of the most common infectious diseases in the world.

Protecting workers from mosquito bites can prevent diseases. Mosquito-borne diseases are those spread by the bite of an infected mosquito. Diseases that are spread to people by mosquitoes include Zika virus, West Nile virus, Chikungunya virus, dengue, and malaria.

Yellow fever virus is transmitted to people primarily through the bite of infected Aedes or Haemagogus species mosquitoes. Mosquitoes acquire the virus by feeding on infected primates (human or non-human) and then can transmit the virus to other primates (human or non-human).

Mosquitoborne Diseases Affecting Travelers Minnesota residents who travel to other countries can return with mosquitoborne diseases such as malaria, dengue, chikungunya, yellow fever, and zika virus.

Hosts include domestic or wild animals and people. The virus develops and multiplies inside the mosquito. The infected mosquito then transmits the virus through its saliva when it bites another, uninfected host. By passing on the virus, the mosquito acts as a “vector” of the disease.
